Fugitive dust—the airborne particles kicked up by construction, excavation, gravel quarrying, and similar activities—would be addressed in two main ways under this bill. It would allow the Division of Air Quality to charge aggregate operations (gravel, sand, and stone extraction sites) an annual compliance fee based on their air emissions, ranging from up to $750 for the smallest emitters to up to $4,500 for the largest, with the Air Quality Board taking over authority to set these fees by rule starting in 2028. Separately, the bill would require "fugitive dust facilities"—commercial sites larger than a quarter acre that produce dust and are required to have a dust control plan, including quarries, excavation sites, and bulk material handling operations—to post clearly visible signage at their entrances listing the facility name, permit and business ID numbers, and contact information for both the facility owner/manager and the Division of Air Quality. Agricultural operations and road salting/sanding for snow and ice control would be excluded from these signage requirements.
